Clearbit

Accepts a company domain or email domain and returns enriched company metadata by querying Clearbit's proprietary database of 50M+ companies. Uses domain-to-company mapping with real-time verification against public data sources (SEC filings, Crunchbase, LinkedIn) and internal signals to validate and augment company attributes including industry, employee count, funding stage, and technology stack.

Accepts an email address and returns enriched person metadata by reverse-matching against Clearbit's database of 500M+ professional profiles. Uses email-to-identity resolution with cross-referencing against LinkedIn, Twitter, GitHub, and other public sources to infer job title, company, location, social profiles, and professional interests. Includes confidence scoring to indicate data reliability.

Accepts CSV or JSON files containing hundreds to millions of records and processes enrichment asynchronously via job queues. Submits batch jobs to Clearbit's infrastructure, which distributes lookups across parallel workers, deduplicates requests, and returns results via webhook callbacks or polling. Includes rate-limiting, retry logic, and partial failure handling to ensure data consistency.

Accepts an IP address and returns geolocation data (country, city, coordinates) plus inferred company information if the IP belongs to a corporate network. Uses IP-to-ASN mapping combined with Clearbit's company database to identify which company owns the IP block, enabling visitor identification without cookies or tracking pixels. Includes confidence scoring and privacy-safe fallback data.

Pushes enrichment data and company intelligence updates to customer-specified webhook endpoints in real-time as new data becomes available. Uses event-driven architecture where Clearbit's data pipeline triggers webhook events when company information changes (funding rounds, executive changes, technology stack updates). Includes retry logic, signature verification, and event deduplication to ensure reliable delivery.

Provides pre-built plugins for Salesforce, HubSpot, Pipedrive, and other CRMs that automatically enrich lead/contact records with Clearbit data without custom API integration. Plugins use CRM-native APIs (Salesforce REST API, HubSpot custom properties) to read contact/company records, call Clearbit enrichment endpoints, and write results back to CRM fields. Includes field mapping configuration and sync scheduling.

Analyzes a company's website and digital footprint to detect installed technologies (web frameworks, analytics tools, hosting providers, payment processors) and infer firmographic attributes (company maturity, technical sophistication, growth trajectory). Uses web scraping, DNS analysis, and JavaScript fingerprinting to identify technology signals, then correlates with company metadata to build a technology profile. Returns structured technology inventory with confidence scores.

Analyzes company behavior signals (website traffic patterns, hiring velocity, funding announcements, technology adoption) and assigns predictive intent scores indicating likelihood of purchase in the near term. Uses machine learning models trained on historical customer data to weight signals and generate 0-100 intent scores. Includes signal breakdown showing which factors contributed most to the score.
